铅纳米晶掺杂Na2O-B2O3-SiO2玻璃的三阶光学非线性
Third-order Nonlinearity of Lead Nanocrystals Doped Na2O-B2O3-SiO2 Glass
摘要
Abstract
Pb nanocrystals doped Na2O-B2O3-SiO2 glass was prepared by a sol-gel method. The microstructure, size distribution and elemental composition of the nanocrystals were investigated by X-ray diffraction, transmission electron microscopy, selected area electron diffraction and energy dispersive X-ray spectroscopy, respectively. The linear and nonlinear optical properties of the glass sample were analyzed by UV/VIS/NIR spectrophotometry and Z-scan technology, respectively. The results show that the Pb nanocrystals in the size range of 10 to 31 nm, which belong to cubic crystal system, appear spherical, and have a good crystallinity and a well-dispersibility in the glass matrix. The glass sample has a high linear optical transmittance, and little absorption peaks ap-pear in the examined wavelength range. Also, it exhibits excellent nonlinear optical properties. The third-order optical nonlinear pa-rameters calculated areγof 1.67 × 10-16 m2/W,βof 7.02 × 10-11 m/W, andχ(3) of 2.61 × 10-17 m2/W2.关键词
